The present invention relates to different embodiments of lighting fixtures, such as troffers. A lens can be placed between a light engine and a reflector and secured in place by crimping portions of the light engine, reflector, or both to prevent the lens from moving. Troffers according to the present invention can lack a dedicated heat sink, instead sufficiently dissipating heat through the light engine. This can significantly reduce the weight of the troffer. Emitter panels can be directly mounted on a light engine inner surface, or on an internal reflector within the light engine.

A lighting device may include an elongated body having at least one light emission surface. The body has at least one longitudinal groove extending along the elongated body. The groove has a tapered cross-section with a restricted mouth portion for receiving and retaining in the groove a complementary coupling element having a restricted stem portion and an enlarged head portion.

A wall mounted light fixture includes a body at least partially defining a housing. The body has a first side facing an interior of the housing and a second side facing the exterior of the housing. The first side of the body has a plurality of front connecting features and the second side of the body has a plurality of rear connecting features. A light emitter is positioned in the interior of the housing and supported by the first side of the body. A lens is connected to at least one of the front connecting features. A mounting component is connected to at least one of the rear connecting features.

A light fixture includes a housing that defines a first cavity. Further, the light fixture includes a light module that is disposed in the first cavity and is configured to emit light in a first direction. Furthermore, the light fixture includes a light redistribution apparatus that is coupled to the housing and is disposed in the first cavity to receive the light from the light module. The light redistribution apparatus includes an outer collar comprising a body that defines a second cavity. Further, the light redistribution apparatus includes a plurality of redirection segments that are disposed within the outer collar and across at least a portion of the second cavity such that they redirect a portion of the light that is emitted in the first direction towards a second direction and allow a remainder portion of the light to travel unobstructed towards the first direction.

The present invention discloses a primary light distribution structure of a directional light source comprises a lamp cup, wherein the lamp cup is provided with a lamp cap at an end; a heat conducting plate, disposed inside the lamp cup and located at a middle portion of the lamp cup, the periphery of the heat conducting plate being in interference fit with and connection with the lamp cup; a power source, disposed inside the lamp cup and located between the lamp cup and the heat conducting plate, the power source being connected to the lamp cap; a light source plate, fixed to the heat conducting plate by means of a plurality of screws, the power source being electrically connected to the light source plate; and a lens structure, covering on the light source plate. In the present invention, the primary light distribution structure is configured such that a larger beam angle is available.

Examples of the present disclosure are related to systems and methods for lighting fixtures. More particularly, embodiments disclose lighting fixtures utilizing metal core PCB (MCPCB) for thermal, mechanical, and/or optical controls.

A luminaire comprised generally of a mounting plate including a plurality of mounting blocks secured to the mounting plate; and a plurality of LEDs, wherein at least one of the LEDs is positioned upon each of the mounting blocks. The mounting blocks include face portions and may be arranged in a plurality of configurations on the mounting plate.

A method for producing a bent organic light-emitting diode and a bent organic light-emitting diode are disclosed. In an embodiment the method includes providing an emitter unit having an organic layer sequence for generating radiation, providing at least one electrical connection piece, bending the at least one connection piece and the emitter unit into a curved shape and subsequently mechanically fixedly and permanently connecting the at least one connection piece to the emitter unit so that the curved shape is permanently maintained.
